Peptide/Protein Group Inference
Protein groups are identified adopting the method used in MSDaPl [@Sharma2012] in which the parsimonious protein inference implemented is based on the IDPicker algorithm [@Ma2009]. The steps involved in the grouping of the indistinguishable protein groups are as follows:
- Step 1: A bipartitie graph is created with edges between peptides
and their matching proteins.

- Step 2: Peptides that match the same set of proteins are merged into
a single node in the graph. For example, peptides 3, 7, and 9 match
protein A and no other protein.

- Step 3: Proteins that match the same set of peptide are merged into
a single node in the graph. These proteins comprise an
indistinguishable protein group.

In this experiment, we report 6554 protein groups and
60562 non-redundant peptides inferred from
97756 peptides measured.
